IMPROVEMENT IN COOKING-STOVES.

' Specification forming part of Letters Patent No. 42,935, dated May 31, 1864.

ToaZZ whom t may concern.-

Be it known that we, SEBASTIAN FAREs and WILLIAM MILLER, both of Cincinnati, Hamilton county, Ohio, haveinvented a new and useful Improvement in Fire-Doors of Cooking-Stoves 5 and we do herebydeclare the following to be a full, clear, and exact descriptior. thereof, reference being had to the accompanying drawings, makingpart of this Our invention relates to a form 'of door or blower for the tire-front ofa cooking-stove, which combines`- the several advantages of economizing the heat and fuel in the stove, in- .creasin gthedraft, assisting combustion, avoiding the undue heating of the apartment, and preserving the said doors vor blowers from burningout. y

Figure 1 represents the front part of a stove embodying our improvement. Fig. 2 is a longitudinal section of the same. Fig. 3 shows a modification of' our invention.

A represents the tire-place of a cookingstove, A being the grate. B is a sliding hearth-plate. 4 The tire-doors O D have each one an inner plate or box, D, whose side d next tothe grate is so d isposed as to leave a passage, l, between the box D and the front bars ot' the grate A', for the ascent and entrance at all parts of the grate-front, of the draft which has passedA down through the box D. The box D receives fresh air at top through apertures E, t

regulated by means of a register, F. The side d of the'box D terminates somewhat short of the level of the door-bottom, so as to permit the now heated draft-air to ow into a space, 2, whence it may enter the nre-chamber A at all parts of the front and bottom of the grate.

We have described our improvement in connection witha grated cooking-stove adapted for burning stonecoal, that being the class of stoves for'which it is particularly designed;

but our improvement is not necessarily re-l -vention being manifestly applicable to every form of cooking-stove.

A modification of our invent-ion may con sist ot' a single detachable door or blower.

Fig. 3 having the precise construction of the.

tre-door C D, except in not being suspended by. hinges to the stove front.

Operation: The tire being kindled, the hearth B being drawn back and the fire-doors C D C D being closed, and the register F bcing opened, .the cool exterior-air will pass down theboxed interiors D D of the fire-doors, so as to keep said doors cool, which on their part so heat the said air as to assist combustion and prevent the entranceof -eool air into the flues. The space 1 between the boxes D D and the grate-front permits acurrent of the entering air to pass up between .said boxes and the re, so as to a'ord a sufcient ingress for the draf t at various parts of the grate, even although a portion thereof may become choked with. ashes, and so as to preserve the said boxes from becoming burned out.

Ve are aware that reedoors ot' cookingstoves have before been so constructed that the air to support combustion will pass through them. This, therefore, we do not broadly claim; but,

Having thus described our invention, what we claim .as new therein, and desire to secure by Letters Patent, is-

The combination of the box-door C D with a register, E F, at top thereof, and partition d, the latter being set at some distance from the back of the door or front of the grate, and all heilig constructed and arranged as dcscribed.

In testimony of which invention we hereunto set our hands.
